AUTOMATIC CUT-OFF FOR CISTERN-PIPES.

SPECIFICATION forming part of Letters Patent No, 397,416, dated February 5, 1889.

Application filed August 1], 1887. Serial No. 246,725. (No model.)

To all whom it may concern.-

Be it known that I, EDWARD UAWTHORNE, a citizen of the United States, residing at Darlington, in the county of Lafayette and State of \Visconsin, have invented new and useful Im lrovements in Automatic Cut-Olii's for (.istern-Pi pes and I dohereby declare the following to be a full, clear, and exact deseript ion thereof.

The invention relates to improvements in automatic cut-offs for cistern-pipes; and it consists in the construction and novel combi nation of parts hereinafter described, illustrated in the accompanying drawings, and pointed outin the claim hereto appemled.

In the drawings, Figure l is a central vertical section of a device cmbodyingthc invention. 'hig. 2 is a side view of the same. Fig. 3 is a side view of the float detached.

Referring to the drawings by letter, M N O L represent a receptacle provided with the central vertical partial partition, T, that rises from its floor to near its top.

K is a water-inlet pipe opening centrally into the receptacle thmugh its roof.

H is an outlet \Vftlbl'jillPG extending to a tank, (not shown,) andI is a waste-pipe. The pipes H and I open from the floor of the receptacle on opposite sides of the partition T.

B is a director-plate fitting snugly within the receptacle, provided with the side flanges, D, and secured centrally to the shaft A,which is journaled in the sides of the receptacle immediately above the partition T. The said plate is provided with a transverse central re-entrant angle, E, in its line of attachment to the shaft A.

R is a crank-arm secured to one end of the shaft extended outside its journal, the lower end of which arm is pivoted to the upper end of a vertical rod, S, to the lower end of which is hung a float, V, preferably of sheet metal, and of a conical form with a small aperture in its bottom. The risin water will thus have access to the interior of the float, so as to compress the air therein and send the float upward suddenly when the valve begins to move, thereby instantaneously changing the flow of water.

P Q is a guide-staple secured to the outside of the receptacle and preventing the rod S from leaving the side thereof. The float is in the tank with which. the pipe H connects, and when the water rises sufficiently high in said tank. the float, the rod S, and the arm R will reverse the director-plate in the well-understood manner, and will direct the inflowing water into the waste-pipe I. The flanges D prevent the water from flowing off of the sides of the director-plate, and the re-entrant angle causes the water to drop in a more nearly vertical direction from the directorplate into the pipe H or the pipe I. The guardstaple I Q is extended horizontally for the reason that as the crank-armR turns upward the rod S mustmove laterally outward in the tank. Thus the said staple, while preventing the rod from moving away from the side of the tank and bending or breaking its pivot with the crank-arm, in no wise interferes with the free motion of the parts.

Having described my invention, I claim In an automatic cut-off, the combination, with the receptacle provided with the central vertical partial partition, T, the inlet-pipe opening centrally in the top thereof, the outletpipes opening into the bottom of the receptacle on opposite sides of the partition T, the shaft A, journaled in the sides of the receptacle at the top of said partition and provided with the crank-arm R outside of the receptacle,and the dofiector-plate provided with the transverse re-entrant angle E and side flanges, I), and secured to said shaft within said angle, of the float V, having a conical form and provided with a small aperture in its bottom, the rod S, pivoted at its upper end to the end of the crank-arm K, and the horizontallyextended guard rail or staple P Q, preventing the rod S from leaving the receptacle and bending or breaking its pivot, yet not ob structing the free motion of the parts, substantially as specified.
